PROBLEM TO BE SOLVED: To reduce higher harmonics distortion. SOLUTION: This track and hold circuit comprises a MOS transistor switch 3 and hold capacitor 4, and higher harmonics distortion is reduced by constituting the circuit so that electric charges accumulated in a gate oxide film capacitor of the MOS transistor of which the bulk potential is varied in the same phase as an input signal Vln and a capacitor between a gate and a source of the MOS transistor do not depend on input voltage.
